Ok. well it appears as if I need to just plug the holes and redrill. what type of plug should I use to fill the holes with and what epoxy? also, when I redrill, do I put the motor on the transom with the top two bolts in the bottom two holes of the top four in the motor and then drill which hole in the bottom?


If I understand what you're saying that's how I planto approach it.
1) take motor completely off and I would pack the hole with fiberglass matting soaked in epoxy, gelcoat, and sand smooth.
2) mount the engine on the transom using the top two bolt holes at the desired height and use the mounting holes of the engine as my guide/template for where to drill the bottom holes. (I don't have the diagram in front of me but I think I am going for the green holes so they are as high in the splash well as possible.
3) remove the engine, blob marine silicone in the holes then replace the engine and bolt everything tight.
